Installing Ubuntu 32-bit

Server Installation Requirements

The Dell Proximity Printing Solution (DPPS) server requires the following:

• A hardware or virtual server that can install Ubuntu 8.10 Desktop

Edition (32-bit).

• At least 2 GB of RAM and a 2 GHz Dual Core processor.

• RAID-5 storage setup.

NOTE: The hardware requirements may be higher if you have a large setup; for

example 100+ buildings or 1000+ printers.

• An active external internet connection for the DPPS server.

• The server administrator must have operational knowledge of Linux based

operating systems, particularly Ubuntu.

• The server must be identifiable by the domain controller as a trusted

system, otherwise the DPPS server may not be able to join the domain.

You must have the following information:

• The workgroup/domain name used in your network environment.

• The Realm used in your network environment.

• The domain name you want to use for the system that will be hosting

the server.

• The Fully Qualified Domain Name (FQDN) for the server you wish to

set up.

• Address of the domain controller/KDC.

• Static IP Address for DPPS server.

NOTE: For more information on workgroup, domain, Realm, DNS, SMTP,

routing, etc., contact your network administrator.

7 DPPS – Installation Guide

Installation Notes

• All the commands used are case sensitive. Using a different case may cause

unexpected results.

•The

sudo

prefix executes the command following it in administrator mode.

• GEdit is a text editor.

• Any text prefixed with # is a comment.

Installing Linux and Setting a Static IP Address

You must create a server install using Ubuntu 8.10 Desktop Edition (32-bit).

After the installation is complete, you must set a static IP address for the

DPPS server. If the setting for static IP are lost after rebooting, follow the

steps below to hard-code the information.

1

Type the following command in a terminal window:

sudo update-rc.d -f NetworkManager remove

2

Restart Ubuntu.

3

Type the following command in a terminal window:

sudo gedit /etc/hostname

4

Delete the existing text from the document and then type the FQDN.

5

Save the document and exit GEdit.

6

Restart Ubuntu.

7

Type the following command in a terminal window:

sudo gedit /etc/network/interfaces

8

The network interface file opens. Type the addresses used by your

environment where applicable. Your file should look similar to

the following:

# This file describes the network interfaces

available on your system

# and how to activate them. For more information,

see interfaces(5).

# The loopback network interface

auto lo

DPPS – Installation Guide 8

iface lo inet loopback

# This is a list of hotpluggable network

interfaces.

# They will be activated automatically by the

hotplug subsystem.

mapping hotplug

script grep

map eth0

# The primary network interface

auto eth0

iface eth0 inet static

address 192.168.0.100

netmask 255.255.255.0

gateway 192.168.0.1

9

Save the document and exit GEdit.

10

Type the following command in a terminal window:

sudo ifup eth0

You may see an error message regarding unable to resolve an address.

Ignore this error as the next step corrects it.

11

Type the following command in a terminal window:

sudo gedit /etc/resolv.conf

12

Delete the existing text from the document and then type:

nameserver

IP Address of your DNS server

You can type all your namespaces in the same format. Each namespace

must be typed in the new line.

13

Save the document and exit GEdit.

14

Restart Ubuntu.

15

Type the following command in a terminal window:

sudo gedit /etc/hosts

16

Use a # to comment out all the line till the first blank line.

9 DPPS – Installation Guide

17

Type the following in a new line after the commented lines:

127.0.0.1 localhost

This forces the server to look at the DNS settings for DNS information,

allowing a more dynamic setting.

18

Save the document and exit GEdit.

19

Type the following command in a terminal window:

hostname -f

If this command does not return the FQDN, contact Dell Pro-Support

for assistance.

20

Restart Ubuntu.

21

Verify that your settings are retained. If the settings are lost, contact Dell

Pro-Support for assistance.
